The SSH port is the port used by the Secure Shell (SSH) protocol for establishing secure connections for remote administration and file transfer. The default port number for SSH is 22. This port is specifically associated with the SSH protocol, which provides secure communication between networked devices, allowing users to remotely access and administer systems securely. While the default port number for SSH is 22, there are occasions when it is run on a different port for testing or security reasons. It is also recommended to change the default port number to enhance security and avoid brute-force attacks. The SSH protocol ensures the confidentiality, integrity, and authenticity of the data exchanged between the client and server. By utilizing port 22, SSH provides a secure channel for managing routers, server hardware, virtualization platforms, operating systems, and file transfer applications.
